eṣa svayaṃ-jyotir ajo 'prameyo mahānubhūtiḥ sakalānubhūtiḥ /
eko 'dvitīyo vacasāṃ virāme yeneṣitā vāg-asavaś caranti //

*35. Atman* V. Pure Jiva-Atman. *Immeasurable etc.* Not possible to be known by the senses and other means, of limited understanding, capable of cognising all things, of one homogenous nature, rid of physical body, beyond the range etc.

D. Paramatman (Myself) is perfect light, the unborn one, incomprehensible, omniscient, all-blissful, individual, absolutely Supreme, where words get stopped, and impelled by whom all the functions of speech come into being and find their use.
